Unity Linux 20.1070a Security Update: kernel (UTSA-2026-146305)

high Nessus Plugin ID 372502

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-146305 advisory.

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nft_compat: ebtables emulation must reject non-bridge targets

xtables targets return netfilter verdicts: NF_ACCEPT, NF_DROP, and so on. ebtables targets return incompatible verdicts: EBT_ACCEPT, EBT_DROP, ... We cannot allow fallback to NFPROTO_UNSPEC.

ebtables doesn't permit this since 11ff7288beb2 (netfilter: ebtables: reject non-bridge targets) but that commit missed the nft_compat layer.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
